Advantages of Rice Non woven Fabric
1. The specialized non-woven fabric has micropores for natural ventilation, and the highest temperature inside the film is 9-12 ℃ lower than that covered with plastic film, while the lowest temperature is only 1-2 ℃ lower than that covered with plastic film. The temperature is stable, thus avoiding the phenomenon of high-temperature seedling burning caused by plastic film coverage.
2. Rice seedling cultivation is covered with specialized non-woven fabric, which has a large humidity change and does not require manual ventilation and seedling refinement, which can significantly save labor and reduce labor intensity.
3. Non woven fabric is permeable, and rainwater can enter the seedbed soil through non-woven fabric during rain, which can utilize natural rainfall while agricultural film cannot, thus reducing watering frequency and saving water and labor.
4. The non-woven fabric covers the seedlings, which are short, strong, neat, with many tillers, upright leaves, and darker leaves.
5. Reduce environmental pollution. The service life of special non-woven fabric for rice seedling cultivation is generally 3 years, which is equivalent to agricultural film. But because it is made by hot pressing polypropylene matrix, it is easier to degrade than agricultural film under physical effects such as sunlight exposure. Moreover, it is breathable and permeable, and even if some fragments enter the soil, it will not cause negative effects such as blocking soil moisture and nutrient transmission like agricultural film, so its pollution to the environment is much lower than that of plastic agricultural film.
6. Improve the yield per unit of rice. Due to the strength of non-woven fabric dry raised seedlings, it is beneficial to increase rice yield, generally by 2-5%.
7. The light transmittance of non-woven fabric coverage decreases, and the average light transmittance under dry seedling plastic film coverage and non-woven fabric coverage accounts for 76% and 63% of atmospheric light, respectively, with little difference between the two; Under the conditions of water seedling cultivation, they only account for 61% and 49% of atmospheric light, respectively. Perhaps due to the significantly higher soil moisture in water raised seedlings compared to dry raised seedlings, there is a noticeable increase in condensation, reduced transparency, and decreased light intensity. Non woven fabric covering is suitable for dry seedling cultivation.
Application of non-woven fabric in the industrial and agricultural industries
1. The construction of artificial turf requires 15-25g of white non-woven fabric, which has insulation properties to prevent grass seeds from splashing out of the soil during rain. 15-25g of white non-woven fabric has the function of water permeability and breathability, allowing water flow to penetrate into the soil during rain and watering. The characteristics of non-woven fabric include biodegradability, no damage to the soil, environmental protection products advocated by the country, wear resistance, water absorption, anti-static, soft breathability, and is cheaper than grass curtains.
2. Genuine leather sofas will be sealed with non-woven fabric, which can be of good or bad quality. Generally, high-quality genuine leather sofas are sealed with high-quality black non-woven fabric, while sofas produced by small companies are usually sealed with low-quality black non-woven fabric.
3. Large and medium-sized canopy coverage: Hang one or two layers of non-woven fabric with a specification of 30 grams or 50 grams per square meter inside the large and medium-sized canopy as a canopy, keeping a distance of 15 centimeters to 20 centimeters wide between the canopy and the canopy film, forming an insulation layer, which is conducive to winter and spring seedling cultivation, cultivation, and autumn delayed cultivation. Generally, it can raise the ground temperature by 3 ℃ to 5 ℃. Open the canopy during the day, cover it tightly at night, and close it tightly without leaving any gaps during the closing ceremony. The canopy is closed during the day and open at night in summer, which can cool down and facilitate seedling cultivation in summer. A non-woven fabric with a specification of 40 grams per square meter is generally used for creating a canopy. When encountering severe cold and freezing weather in winter, cover the arch shed with multiple layers of non-woven fabric (with a specification of 50-100 grams per square meter) at night, which can replace grass curtains. The above is the introduction. For more details, you can call below to inquire about the non-woven fabric used for seedling cultivation.
